PNEUMATIC CORD TIRE.

Application tiled January 26, 1916.

To all whom it may concern Be it known that I, Clmniins L. Ancunn, a citizen of the United States of America, residing at Minneapolis, in the county of ennepin and State of Minnesota, have invented certain new und useful Improve- I ents in Pneumatic Cord Tires, of which the followingis a specification, reference being had therein to the acconipanyingr drawin This Invention relates to pneumatic tires for automobiles and like vehicles und hns special reference to n cord tire.

The principal object of this invention is the production of a pneumatic cord tire which is so constructed as to provide etlicient beads thereon for facilitating the retention of the tire upon the folly or rim of a wheel.

Another object of this invention is the production of a pneumatic cord tire wherein the cords have their end portions looped so as to fit about one or more wire cables or cable stri s so as to constitute n plurality of beads or facilitating the retention of thc tire upon the felly or rim of n wheel.

ith these and otherobjects Vin view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drnwing'like charneters of reference indicate like views in the several parts, wherein:

Figure 1 is a transverse section through the complete pneumatic cord tire as constructed in accordance with this invention. Fig. 2 is an, enlarged fragmentary sectional view through n portion of the tire illustrating ver clearly the construction of one ot the bea. s. Fig. 3 is a fragmentary sectionalJ View through n slightly modified forni oi' the tire, illustrating another way in which the bead may be formed. Fig. 4 is a detail fragmentary perspective vieu' of one ot' the cablestrips. Fig. 5 is a fragmentary perspective View of n portion of the tire, illustrating the manner in which the in vers of cords extend in relation to each other.

Referring to the accompanying drawing by numerals it will be. seen that l designates extending cords ing cords 2, while tending cords 3 the outer transversely cxit upon the longitudinal Specification of Letters Patent.

cords 2, clearl shown in Figs. 1 and By this construction it will be seen that the longitudinal cords 2 are interposedbetween the transversely extending cords l and 3, thereby forming n very strong body for the tire. t

The ends of the inner transversely extending cords l are looped over :is shown ut 4, :is are the ends of the transversely extending cords 3y :is shown at 5. Therefore, it will he seen that the looped ends 4 and 5 of the cords 1 and 3 will provide the longitudinallyI extending iockets (j.

-The cable strip i llas a looped portion S fitting about the wire cable i), which cable will form a very rigid body for the cable Strip 7. As runny of these cable strips desired muy be positioned wit-hin the longi tudinfilly extending pockets 6 formed by the looped portions' 4 and 5 of the transversely extending cords, as will till these pockets. After these cable strips ha vingtheir cables 9 nrc positioned within the pockets und are wedged therein, :t suitable filler, such for instance as soft rubber, us shown at l0, may then be forced into or positioned within the pockets 6 so as to lill the sume, :is clearly shown in Fig. 2, thereby preventing any telidency of the cable strips to shift or the beads to lose their correct shape after thc tirc has been completely nssembled. It will he seen that the longitudinal cords 2 uhll also be interposed between the looped ends of the transversely extending cords, as shown in Figs. 1 and 2, thereby holding the looped ends 4 und 5 in their correct spaced relation relative to each other. l

The side walls 11 are then positioned. upon the enter transversely extending cords '2S so as to allow the heels 12 to be positioned upon thc looped ends of the transversely extending cords, whereby these-looped ends und the hee-ls 1E), will constitute elicicnt beads which muy be positioned upon the rim, or folly of n `.vhcel so as to support the pneumatic tire iu engagement therewith. 'lhe breaker cords 13 nrc then positioned upon the trend portion.. of the outer trans-1 versely extending cords 3 and are held iii position by means of the tread 14 which ist` positioned upon the breaker cords 13, thl transversely extending cords 3, and the sid walls 11.n y

It is obvious that after these several elements have been positioned upon each other the entire tire if so desired, may be rubberized so as to constitute an eliicient und compact one-piece pneumatic tire which is so constructed as to present a very yl'eldeblc and resilient tire, While the cords extend so as to minimize the possibility of the tire being punctured or blown out when in operation.

As shown in Fig. 3, a slightly modified form of the device may be employed, whore in the outer transversely 'extendin cords 3 tit u on the longitudinally exten ing cords 2f. he inner .transversely .extending cords 15 are bulged inwardly, as shown at 16, and are then ooped over as indicated at 17, whereby the looped over portions of the inner transversal extending cords 15 will pass over the en s of the outer transversely extepding cords 3' since the ends of the transverselyv extending cords 3' terminate substantial y evenly with the longitudinali y extending cords 2. The cable stri 7 may be positioned so as to fill the bulge portion 16, while another cable strip 7 may t upon the outer'transversely extending cords ad- 'acent their ends so as to engage the ends 18 of the looped over' portions 17 of the transversely extending cords 15. The heel 19 may be positioned upon the looped over ortions 17 of the transversely extending cor s 15, at which time the entire device may be rubberized so as to constitute a. substantially onepiece structure, since the side wall 20 of the eel 19 will fit upon the outer transverselyv 3' as clearly shown in Fig. 3; Thus, it will be seen that since the looped over portions 17 of the transversely extending cords f1.5 provide suilicient space for the interposition of a number of cable strips and cal `es a very strong bead has been provided for facilitating the retention of the complete tire upon the rim or lfolly of a wheel.

From the foregoing descriptionit will bc seen that a xery simple and ellicient pneumatic cord tire has been produced which is so constructed as to remain in its'corrcct shape after being assembled and which is foi-med 'so as to cause the looped ends of tlic transverse cords to be reinforced by carrying cable strips to constitute cflicient beads for the purposes hcrcinbcfore presented.
